Method of borehole compensation of earth formation characteristic measurements using depth measurements

摘要

A borehole tool (150) has a depth measurement, a transmitter (160) and receivers (170) spaced apart from the transmitter which generates waveforms with receivers responding. Differential time measurements are obtained from the borehole tool. A receiver array differential time measurement is generated for a depth interval spanned by the receivers. Transmitter array waveforms corresponding to the transmitter are selected and acquired when the transmitter is located within the spanned depth interval.
